Title: Drive circuit for a brushless motor
Inventor: STEPHEN GREETHAM
IPC: H02P27/16
Filed: 2020-12-03
Abstract: Drive circuit for brushless motors, comprising: a bridge converter of bidirectional switches SW1-4 connected to the motor’s phase winding 21; and a controller 38 that configures the switches to different states (Figs. 4-8, 11). Bidirectional switches have four states (Fig. 3): ON, bidirectionally conductive; D1, conductive in a first direction; D2, conductive in a second direction; and OFF, non-conductive. A first configuration configures a pair of bidirectional switches in a diode state and another pair in the OFF state (Fig. 7c). A second configuration changes the pair of switches in the diode state to an ON state (Fig. 7d). The controller may receive a signal indicative of the rate of change of converter current and choose switch configuration dependent thereon. The controller may receive a signal indicative of a voltage polarity and chooses a diode state D1, D2 dependent thereon. A third configuration may prevent current from flowing through the phase winding. The controller may switch to the third configuration during a zero current. The arrangement removes the need for a rectifier and prevents reversal of current due to back EMF.
